Developed with the average 3800 enthusiast in mind, this calibration has been designed and dynamometer tested and proven for the following vehicle modifications installed:
- 3.4” - 3.20” pulley
- Cold air induction system (brand not applicable)
- Cat-back exhaust system (brand not applicable)
- Premium fuel (91+ octane) *NOTE: This calibration is NOT intended for stock 3800 powered vehicles. Additionally, premium fuel IS required.

IMPORTANT NOTES:
- The Model Year and Vehicle Identification Number (VIN) of your car are required information that needs to be filled in at the bottom.

- A core charge will be placed on the PCM. The core charge is 100% refundable with the return of your original working PCM within 14 days of receiving your v1.0 PCM. Also, the PCM core must be the same service number that we send you. If your core is not returned within 14 days, your refunded core charge is forfeited.
All information MUST be filled out, and all required paperwork MUST be in the returned package. Your core MUST be shipped via UPS or FedEx ONLY, and must have a “No Signature Required” release on it to avoid delays in your refund.

- You also have the option of keeping your core, and the core charge will be added to your total.

- We now have the option to forego the core charge and the customer can ship us their PCM to be reprogrammed. You will still need to print out and fill in the same core return form above when mailing us your PCM.
